AF-Boosted MF
In this focus mode, you can focus manually most of the way and let the camcorder finish focusing automatically. This is very convenient when you want to make certain that your 4K recordings are in sharp focus.
Additionally, with this mode, if the camcorder cannot evaluate how to adjust the focus, it will not perform unreliable focus adjustments. This results in an overall more stable focusing operation than with continuous AF.
